Which statement describes the use of tcptraceroute?

• A. tcptraceroute is a network diagnostic tool used to trace the path packets take to a network host.
• B. Nessus is a password manager.
• C. Smurf attack uses ICMP floods.
• D. XSS Reflection is a form of phishing.

Answer: (A)

tcptraceroute is a network diagnostic tool that traces the route packets take to reach a host by sending TCP probes (often to a common port) and recording each hop along the path. This makes it possible to see how data would travel to a destination even when firewalls or routers block the traditional ICMP or UDP probes used by classic traceroute. By observing where responses stop or change timing, you can identify routing issues, firewall restrictions, or devices that affect the path. The other statements describe different concepts: Nessus is a vulnerability scanner, not a password manager. A Smurf attack uses ICMP floods, which isn’t about tracing a route. XSS Reflection is a form of cross-site scripting, not phishing.
